On the morning of Tuesday, March 17, 2026, the City of Cayce will be conducting water system testing near the Cayce Water Treatment Plant to ensure future system reliability for a planned upgrade.

The work will require the flow of water to be reversed in some areas of the system, particularly near Moss Creek, Concord Park, and the 12^th Street corridor between Frink Street and I-77. 

When this work is done, there is the potential for brown water to be noticed from faucets. This discoloration is caused by harmless minerals, such as iron and manganese, that can become loose in water lines during water system testing. This is not an indicator that the water is unsafe to consume, and the discoloration will be temporary. 

If you notice any discoloration, run cold water from a faucet for several minutes until it clears. It is recommended to avoid washing light-colored laundry until the water runs clear.

If any of our Cayce citizens or businesses have questions, please contact Cayce Utilities at 803-550-9542.
